You forgot to put your EnvMap material into the "Background Material" field!

You need to put your EnvMap into the EMISSION chanel, not the diffuse color ;)
Set it to uniform with a value of 10.000.000, the gamma to 1.0 and play with the B value to have it brighter or darker...

My fault, I forgot something!

You need to uncheck "captured simulation" and enable "Extra atmospheric"!
By this no Sky will be used, but only the sun.

At the moment you have the Sky and EnvMap blended together. Because the Sky is way brighter, you only see it, and not the EnvMap!

You can tweak the "Background material Weight" parameter to raise EnvMap overall power...
